Love's spate of irate tweets started with accusations that Dave Grohl seduced and had sex with her 19-year-old daughter Frances Bean Cobain, whom he's known since her infancy. Grohl, who was Nirvana bandmates with Francis Bean's father, Kurt Cobain, vehemently denied the accusations, Rolling Stone reported.

"I'm not mad at her, him i am about to shoot, dead," Love tweeted, adding, "its dave that I'm going to kill." She claimed her estranged daughter' roommate had told her that Grohl tried to seduce Frances and accused him of being "sexually obsessed" with her late husband.
